Speed limits not applicable to emergency or public safety vehicles.

The prima-facie speed limitations set forth in section
4511.21 of the Revised Code do not
apply to emergency vehicles or public safety vehicles when they are responding
to emergency calls and are equipped with and displaying at least one flashing,
rotating, or oscillating light visible under normal atmospheric conditions from
a distance of five hundred feet to the front of the vehicle and when the
drivers thereof sound audible signals by bell, siren, or exhaust whistle. This
section does not relieve the driver of an emergency vehicle or public safety
vehicle from the duty to drive with due regard for the safety of all persons
using the street or highway.
